Electric OU: Supplement: The Delayed Trigger Timebase of the HP180a
Here I do a quick demo of some of the capabilities of the 1821A Timebase and Delay Generator plugin of the HP180a scope. I use it to display two timebases at once: 0.2 ms/div and 2 us/div, and determine the frequency of Tar Baby’s feedback oscillations. Fooling around a bit lets us see the beginning and ending of the feedback trace.
